Remuxing the palmas interrupt to gpio_wk16 instead of sys_nirq1
makes the palmas interrupt work just fine configured with active-low
or active-high with the internal pulls. So palmas.c is doing the
right thing, and the issue configuring palmas interrupt active-high
with sys_nirq1 on omap5 is somewhere between omap wkupegen and GIC.
